Test Code WBC CoQ10 CoEnzyme Q10 Level, Leukocytes

Clinical System Name

CoEnzyme Q10 Level, Leukocytes


Leukocyte, Intracellular Coenzyme Q10



Coenzyme Q10 is produced by the body and is necessary for basic cell functioning. Deficiencies in coenzyme Q10 can be primary or secondary. Primary coenzyme Q10 deficiency is a rare autosomal recessive genetic condition with clinically heterogeneous presentation that can include:

  •     encephalopathy
  •     seizures
  •     ataxia
  •     cardiomyopathy
  •     renal failure
  •     cerebellar atrophy
  •     Leigh Syndrome
  •     growth retardation
  •     delayed motor development
  •     lactic acidemia
  •     hypergonadotropic hypogonadism/myopathy

These individuals will have decreased levels of coenzyme Q10 in plasma as well as in skeletal muscle. Secondary coenzyme Q10 deficiency has been seen in individuals with several chronic disorders such as heart conditions, muscular dystrophies, and mitochondrial disorders (such as MELAS and Kearns-Sayre). Additionally, some prescription drugs can lead to a decrease in coenzyme Q10 levels.
